At the start of the charging process, the charge
level display is shown in the Instrument Display
with a charging prediction. The charging predic-
tion either refers to the predicted charge level at
the set departure time, or the time at which the
high-voltage battery will be fully charged.
% Depending on the temperature, the fan and
batt

ery cooling system may audibly switch on
during the charging process.
% If the vehicle is idle for lengthy periods and
connect
ed to the mains supply, the high-volt-
age battery will be recharged automatically as
needed or when electrical consumers are
activated (e.g. the pre-entry climate control).
% The vehicle is equipped with an electrical fuse
whic
h protects it against overvoltage in the
mains supply. This electrical fuse may trip dur-
ing severe thunderstorms, for example, and
may cause the fuse in the building to trip or may interrupt the charging process. These
functions pr

otect the vehicle.
Aser the fuse in the building is switched on
again, the charging process resumes automat-
ically. Following an interruption in the power
supply without the fuse in the building being
tripped, it may take up to ten minutes for
charging to resume automatically. Ending the alternating current charging process

DANGER Risk of deat h when charging at a
damaged socket
The charging process uses high voltage.
If t
he charging cable, the vehicle socket or the

ing, abr
ading or driving over the cable. 
Have a damaged vehicle socket replaced
at a q

ualiNed specialist workshop as
soon as possible. 
Never connect the charging cable to a
damag
ed vehicle socket. *

charging cable and charging cable con-
nector During the charging process, the charging
cable and c
harging cable connector can heat
up within their permissible limit values.
The permissible limit values are inOuenced by
the following factors:
= the power supply system and the charging
cable are not damaged
= the instructions for handling the charging
cable and the control element on the
charging cable have been observed
